28 provided thereon. The cable 24 is tightly drawn between the two members [4, being'fixedly I secured to the end panels 36, and constitutes a flexible horizontal cable wherebytthe two door sections may be simultaneouslyoperated ii For an understanding of the construction of the telescoping door, attention is now directed more specifically to Figures 4 and 5, wherein it willbe seen that each door 'h'alfconsists of an end door panel 3 6 thesame' includingjan' inner panel member st 'encased' in a "pair of parallel side panel members 34, the inner member 32' being notched or fcut away "what maybe termed its rear end to provide a recess Biiyas shown best in Figure 3; Therecess is employed forattaching to the end panel 3!! a parallel bar connecting linkage' 'as setforth hereinafter.

In addition to-the end panel 30 previously 7' described, each door halff-urth er'includes other panel sections 38, 49' and 42, each-of which coinprises spaced parallel walls 44,45 and id-"re spectively. These side walls are secured together in fixed relationby ameans to':behereinafter setforth, so that the panel "section 43 constitute ing the rear panel of the' door assembly is slidably received between theh'ousingside'wallwi E the next panel section 45 being slidably received in the section 42, the section -38 being slidably received in the section diL-whilethe end panel 3% is slidably' received: within the panel33il The arrangement is such that the panel-sections of the. door. may be selectively disposed in their telescoped or'retracted position, as shown in full lines in Figure 4; thereby permitting free opening of the space between the doorway post l4 between the. endsof .the "housing .wall. it. However, the door may bieppehedfihto the full line position ,shown in Figure 55, 017 the "dotted line position shown in Figure {Lso'asf to close the door opening. It will be readily understood that the size of the panel'sections may be such that one telescoping door panel assembly will be sufficient to close the entiredoor opening although it is'preferred to provid'e'for" large door openings the arrangement shownin Figure "1", wherein the end panels '38 of twodoor halves: meet at the middle. of the opening andv in endwise abutting engagement. as shown clearly-inFigures 1- and-3.

In addition, the" door sill 2B -is provided with lateral shoulders 52 whi'c. are horizontally an; opposite sides of the. portion 50, and which in' turn serve as door sills for the lower edges of*tnesmewausutf the panel sections3'oi The lower edges of] the side walls lii-andds of the panels 40 and 42', assho'wn in Figure 2 are disposed in the same horizontal plane and on opposite sides of the member 20.

The end panels 30 are directly mounted upon and slidable upon the rigid supporting member 22 and for this purpose are provided with notches or recesses 54 in'the upper edge of the member 32, for the reception of upper and lower sets of transverse axles 55 and 58, which are provided withguide; rollers and 62;, which respectively rest...upon the: upper an ,lower surfaces of the member 22, for supporting the weight of the are connected by transversely disposed pins 64.

- As showndnrFigure 3 these pins also serve to guide and.tension cable 24; however, this function, although a desirable one, could be eliminated without departing from the spirit of the invention; Adjacent" their upper and lower-rear edges," the sidewalls of each of the panel sec-' tions38, 40 and 42' are rig'idly connected to" each other'and ins'paced relation as-by transversely disposed rods or bolts 66. The position of the bolts'6'6, and the pins fil-is such as not: to interfe're withthe nesting'of'the telescoping sections inftheir'colla'psed or stored position; connecting-parallel bar linkage'is provided -for securing the various sections of each ofthe door assemblies together, and for permitting but limiting relative telescoping movement between the p'a'nel 'sections. *For this purpose, as shown best in'Fig'u'res 3 and5, a vertical or longitudinal slot 68 is disposed in the housing member M this slot being "preferably substantially iden= ticalwith' and complementary to the previous= ly d'escribed slot' 3fi in the. end panels 32. Kplurality' of-transversely disposed pins 70' are fixedly secured in"any-'desir'ed manner in the member lid and extendingacro'ss the slot 68 to constitute axles or pivot-pins" forthe connecting b'ar' linkage. 'simnanmmms or axles l2 are securedbetween' the side walls 'of the slot 36'and the end panel 38 in substantially the same horizontal plane's'with' the pins .llL'these pins '12 being'retainedas lay-fastening screws 14 extending through the panels! of the'endpanel 30.

Pivotally secured to'the intermediate pin 10,

in properly spaced relation thereon as by spacer washers orthe likelli; are a-pair of parallel bar links 78 and' sll, each comprising a pair of links. At their-opposite ends; the'li'nks 18-and80 are pivotally connected at 82 and 84 respectively with the-ends of alon'ger pair of links 86 and 83 respectively." The other extremities of the links 86' and B8, are r'espectively'pivoted to the upper'and lowermostof-the pivot pins 12 in the slot 36. 'For this purpose, the links 86 and 88 are provided with elongated slots 90 and 92 respectively which thus have a sliding or lost motion'upon' the pins-7Z.- I 1 In a'similar manner, 'a pairof links 94 and 96 arelikeWisepivoted to the central pivot-pin -12 of the end panel BILand-at their other ends are terminally pivoted M98 and I00 .to. the ends of levers I02 and H14, whose-other extremities areconnected as by the elongatedslotslflfi and M8 totlieupper andlower'pins 10; 1

It will .be here noted that the links T8,-i;=94 and 96 are of,equal length,*and are shorter than the links '88; I OZxand. HM which are of equal It"will'thus beiseen that a parallel bar-linkage connects the end panel 30 with: the door post links 18 and 96. links 66 and I02 are provided with registering pins I32, I22,

The links 86, 88 in turn are pivoted to each other at I32, while links I02 and I04 are pivotally connected at I34.

The opposite ends of the link I20 are slotted at I36 and I38 and are pivotally connected at I40 and I42 to corresponding slots I44 and I46 formed in the links 80 and 94. In a similar manner the link H8 is provided with terminal slots I48 and I50 pivotally connected at I52 and I54 to corresponding slots I56 and I58 in the Intermediate their ends, the

slots I60, I62, pivotally connected to each other as by a pivot pin I64, while the links 88 and I04 in turn are provided with longitudinal slots I66 and I68 pivotally connected to each other as at I10.

At this point it should be noted that the pivot I34, not only serve to pivotally connect certain of the links together, but also constitute fastening and spacing means for the side walls of the panel sections 38, 40 and 42. For this purpose, as more readily apparent from Figure 5, each of the pivot pins includes a shaft I12, whichextends between the side walls of the associated panel sections and fixes the space therebetween and is internally threaded at its opposite extremities for attachment to the panel side walls as by bolts I14. Suitable spacing collars I16 are provided loosely upon the shafts I12 between the side walls of the associated panel sections for maintaining the links pivoted thereon in proper relation. As will be further apparent from Figure 5, the links of the shafts I12 and in the spacing sleeves I16 of the various panel sections will vary with the widths of these sections.

In a similar manner, each of the pivot pins I40, I10, I54, I52, I64 and I42 likewise constitute combined pivot pins for the links and fastening and spacing members for the side walls of As shown in Figure 6, the construction of these combined pivot pins and spacing and fastening members is identical with that described in connection with Figure 5.

From the foregoing, it is felt that the operation of the parallel connecting bar linkage will now be readily understood. The linkage will,

maintain the various sections of the door in proper relation to each other during movement collapsed to the extended position, and it is observed that the connecting bar linkage is compactly housed within the telescoping sections themselves. I

From the foregoing, the construction and operation of the .device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art after consideration of the foregoingspecification and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but
